看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。
23Sometimes, having said that, the crystal method of the silicate inclusions is noticed to resemble extra closely The inner framework of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
Most reliable resources found in mother nature exist in polycrystalline kind as opposed to as only one crystal. They are literally composed of an incredible number of grains (modest crystals) packed with each other to fill all space. Just about every person grain has a different orientation than its neighbours. Despite the fact that extensive-vary get exists inside of one particular grain, with the boundary between grains, the ordering improvements course. A normal bit of iron or copper (Cu) is polycrystalline.
《全唐诗》卷七八五载《白雪歌》：“鸟啄冰潭玉镜开，风敲檐溜水晶折。”
They can ultimately generate a wonderful little uniform cluster of atoms, This can be the whole process of developing crystals. The greater they are able to arrive collectively, the more of a development might be seen to the naked eye. Researchers can ascertain what mineral They are really thinking about by how the crystals form.
解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。
Hexagonal �?Characterised by 4 axes, a few of that are equal in duration and intersect at 120 degrees, that has a fourth axis perpendicular to one other three.

Orthorhombic: These are typically rhombic prisms and dipyramids that resemble tetragons but with no sq. cross-sections.
crystal, any stable content through which the part atoms are organized inside of a definite sample and whose surface regularity demonstrates its inside symmetry.
crystal Alteration is variable: absent in lots of crystals, in Some others creating dense sericite aggregates which can clearly show some recrystallization effects to provide coarser-grained white mica. In the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally organized in aggregates. With the Cambridge English Corpus In addition, haloarchaeal cells were being embedded within just salt crystals less than laboratory disorders and subsequently analysed by gentle microscopy. With the Cambridge English Corpus The white clouds (ordinarily sparse) ended up also extensively considered currently being composed of little crystals of water ice, somewhat like cirrus within our ambiance. Through the Cambridge English Corpus They're present in evaporite salt lakes and might be trapped in salt crystals throughout evaporation. With the Cambridge English Corpus Consequently, the cells (organelles and membranes) are ruined mechanically by ice crystals, leading to Demise as a result of cell lysis. From your Cambridge English Corpus The crystals have been Utilized in the 1st or next orders of reflection. With the Cambridge English Corpus Inside our 8xperiments, the crystals were being cubes having a base location of eight e mm. From the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and force.
